Definitions

  • This invention relates to a machine for forming cylindrical bales of crop having a container mounted thereon, for a supply roll of wrap material for wrapping completed bales, with a floor for supporting the supply roll in a wrap material dispensing position.
  • Machines towed by a tractor, for forming large cylindrical bales of hay (so called "round balers") are well known. As the machine advances, the crop is removed from a windrow by a pick-up mechanism and delivered rearwardly to a baling chamber where it is rolled into a bale.
  • a round baler in which a supply roll of web material for wrapping is stored in an open container at the top of the machine. Whilst a completed bale is still rotating the web material is advanced by a pair of feed rolls to the baling chamber where it engages the periphery of the bale to wrap it, the required length of material being severed downstream of the feed rolls. Upstream of the feed rolls the material passes over an idler guide roll mounted on the machine.
  • the container Since the container is at a level above the reach of an operator he must climb up some distance to the container in order to load it.
  • the present invention provides an arrangement whereby a supply roll can be dispensed from a high position, and loaded very easily at a low position.
  • a container has an open side which in the dispensing position is covered by a wall of the machine, the container is mounted for swinging movement about a pivot axis spaced below the floor (when in the dispensing position) between the dispensing position and a lower loading position whereat a supply roll can be loaded into the container through the open side.
  • the supply roll can simply be deposited in the open container without any special mounting procedure to locate the roll.
  • the container supports a guide roll below it, a pair of wrap material feed rolls is disposed below the container and the guide roll engages a said feed roll.
  • the guide roll will swing with the container and in the loading position the wrap material can readily be passed over the guide roll.
  • bale discharge gate 20 of a large round baler similar in construction to that disclosed in our US-A-4,428,282.
  • Extending between and rotatably mounted on opposite sidewalls 22 of the gate are lower rear and lower front bale-forming belt support rolls 24 and 26, respectively.
  • a plurality of bale-forming belts 28 is supported in side-by-side, spaced relationship across the support rolls 24 and 26 and other rolls of the baler and operate in a manner set forth in US-A-4,428,282 to roll crop products, introduced into a bale-forming chamber formed in part by said belts, into a bale.
  • a bale wrapping mechanism 200 is mounted on the rear of the gate 20 for introducing a wrapping material such as plastic sheet or net into the bale-forming chamber for enveloping the bale prior to its discharge.
  • the wrapping mechanism 200 includes a frame 202 including opposite vertical sidewalls 204 provided with forward vertical flanges bolted or otherwise secured to corresponding flanges forming vertical rear ends of the gate sidewalls 22. Tops of the sidewalls 204 are defined by horizontal flanges 206.
  • a wrap material housing 208 has opposite sidewalls 210 joined together by a downwardly and rearwardly sloping top wall 212, a vertical rear wall 214 and a horizontal bottom wall 216 which terminates short of the front of the housing for defining a wrap material passage 217.
  • the front side of the housing 208 is closed by a vertical panel or abutment wall 218 extending between and joined to the gate sidewalls 22.
  • a supply roll of wrap material 220 which is biased, by an arm means including a U-shaped structure 222, toward a comer 224 defined by the juncture of a forward continuation of the bottom wall 216 and the panel 218.
  • the U-shaped structure 222 includes a pair of arms 226 having forward ends respectively pivotally connected to upper forward locations of the sidewalls 210, as at pivots 228, and having rearward ends joined together by a crossbar 230 which engages an upper rear area of the roll of wrap material.
  • a rearwardly projecting crank arm 232 is mounted to the right pivot 228 for rotation with the arm 226 and a spring 234 is coupled between the arm 232 and the right sidewall 210 so as to urge the crossbar 230 against the roll of wrap material 220.
  • the U-shaped structure 222, crank arm 232 and spring 234 are located such that a force is applied to the wrap material supply roll 220 which changes as the material is used such that the force required to pull wrap material from the roll remains substantially constant.
  • the force exerted by the arm structure 222 acts to keep the roll engaged with the bottom wall 216 and panel 318 and to prevent accidental unwrapping of material from the roll.
  • the housing 208 is mounted on the sidewalls 204 by a pair of straps 236 depending from lower rear locations of the sidewalls 210 and respectively coupled to the sidewalls 204 by pivots 238.
  • the housing 208 may be pivoted rearwardly about the pivots 238 to a lowered open loading position, as shown in dashed lines in Fig. 2, permitting loading of a new roll of wrap. It is to be noted that such loading is not only facilitated by the fact that the open position of the housing makes it unnecessary to lift a roll of wrap material a great distance above the ground but also because there is no special mounting procedure needed to locate the roll which is merely dropped into the housing 208 through its open side.
  • a pair of spreader roll support legs 240 is secured to and depends from inner lower front locations of the housing sidewalls 210. Extending between and rotatably mounted adjacent the bottoms of the legs 240 is a wrap material spreader roll 242 comprising a cylindrical roll having spiral flighting (not shown) at opposite ends thereof and with the spirals being of opposite hands for acting on the wrap material to "feed" the opposite edges thereof toward the opposite sidewalls 204.
  • the spreader roll 242 is disposed for rotation about an axis located forwardly of a forward wrap material drive roll 244 which is rotatably supported in the opposite sidewalls 204.
  • a rear portion of the periphery of the spreader roll 242 is located very close to and slightly beneath a forward portion of the periphery of the drive roll 244.
  • a rear wrap material drive roll 246 extends between and has opposite ends rotatably supported by the sidewalls 204 at a location below and rearwardly of the axis of rotation of the front drive roll 244.
  • the drive rolls 244 and 246 include respective elastomeric surfaces which are in tight frictional engagement with each other so as to define a pinch point 256 for gripping wrap material fed therebetween.
  • the drive rolls 244 and 246 form part of a wrap material feed system 260 for introducing wrap material into a bale-forming chamber at an inlet located forwardly of the bale-forming belt support roll 26.
  • the feed system 260 is not described in detail as it does not form part of the present invention.
  • the material feed system 260 includes a wrap material guide assembly 262 for directing wrap material exiting the drive rolls 244 and 246 to the bale-forming chamber, a cut-off knife assembly 264 for cutting off a length of wrap material once wrapping of a bale is near completion, a drive roll drive assembly 266 for selectively driving the drive rolls when it is desired to wrap a bale formed in the chamber and a hydraulically controlled latch assembly 268 associated with the knife and drive assemblies 264 and 266 for selectively cocking a cut-off knife arm 270 while simultaneously effecting engagement of the drive roll drive (this is the condition illustrated) and for selectively releasing the arm 270 for effecting cutting of the wrap material at a location after the drive rolls while simultaneously effecting disengagement of the drive roll drive.
  • a wrap material guide assembly 262 for directing wrap material exiting the drive rolls 244 and 246 to the bale-forming chamber
  • a cut-off knife assembly 264 for cutting off a length of wrap material once wrapping of a bale is near completion
  • the wrap material supply roll 220 will merely rotate in place in the housing 208 as the drive rolls 244 and 246 pull wrap material therefrom thus making it unnecessary rotatably to support the cylindrical core of the roll.
  • the U-shaped structure 222 acts to apply a changing force to the supply roll 220 resulting in a substantially constant force being required to pull wrap material from the roll.
  • the U-shaped structure 222 also acts to urge the supply roll 220 toward the corner 224 and thus serves somewhat as a drag brake to prevent material from being accidentally unwrapped from the roll 220.
  • the structure 222 acts to keep the forward surface of the roll 220 properly aligned for feeding wrap material through the passage 217 and about the spreader roll 242.
